#TUTORIAL WIRESHARK 2.0 SOFTWARE#
At the time we started the project (May 2014) the only software switch that supported OF 1.3 was the CPqD software switch. For our project we developed our own TTP known as the SPRING-OPEN TTP.Īnd so, in our project we needed a switch we could use to support the SPRING-OPEN TTP. The ONF's Forwarding Abstractions WG is working on this topic.
In OpenFlow terms such a HAL is known as a Typed Table Pipeline (TTP). Think of it as the contract between the controller and the switch – the switch supports the HAL and the controller programs the switch according to the HAL. Many of the tables can be abstracted away by creating the right Hardware Abstraction Layer. The controller does not need to know all the tables, registers etc. In reality the hardware switching ASIC has tens of tables. But more importantly the software switch had to emulate the hardware pipeline, so that when we actually moved to hardware switches, there would be minimal changes in the controller. In other words, we needed a software switch that we could put in Mininet, and point to the controller to pretend to be a segment routed network. However, during controller development we mostly relied on a software switch that could emulate the Hardware Abstraction Layer that the Dell team was building the FTOS to support. CPqD Software SwitchĪ little history: The goal of this project was to demonstrate SDN control of segment routing on switching hardware that exists today. But once it is back, login again to configure the OpenFlow instance. You will of course lose your ssh session.
#TUTORIAL WIRESHARK 2.0 UPGRADE#
Once the upgrade is done, reload the box. If you do not wish to use this pre-built VM, you can download from source, and follow the installation directions below. It also includes the recommended Wireshark dissector for OF1.3.4 protocol messages from the loxigen project.
It includes the Mininet network emulator required to run the software switches in a network topology of your choice. This VM has the specific version of ONOS (and its dependencies), the specific CLI, and the specific version of the CPqD OF1.3 software switch required for this project. To get started we recommend downloading the pre-built VM from the link below. The hardware routers are built with Dell 4810 switches. The software routers are built from a version of the CPqD OF 1.3 software switch. For the switches, you have the choice of using software or hardware segment-routers. To try out the prototype, you will need this version of ONOS, and you will also need the CLI that works with this version of the controller.
#TUTORIAL WIRESHARK 2.0 CODE#
The source code for this project is available from the url below. It is built on the previous (internal) release of ONOS (Sept 2014). SPRING-OPEN is not built on the latest version of ONOS (Avocet). UPDATE: SPRING-OPEN has not been supported since 2016.
